Answer:

P = 20x - 12

Step-by-step explanation:

The Perimeter of a Rectangle is 2l + 2w, where l is the length and w is the width.

Now, let's substitute the given values.

2(8x - 9) + 2(2x + 3)

= 16x - 18 + 4x + 6

= 20x - 12                     <--- This is the answer

Hope this helps!

The volume of a prism is 378CM2 one of the faces are 27cm 2 the edge is x, x=?<br> mathswatch.
olga_2 [115]

The length of the prism is 14 cm if the volume of the prism is 378 cubic cm and face area is 27 square cm.

<h3>What is volume?</h3>

It is defined as a three-dimensional space enclosed by an object or thing.

The question is incomplete.

The complete question is in the picture please refer to the attached picture.

We know the volume of the prism can be calculated:

Volume = base area×length

378 = 27x

x = 378/27 = 14 cm

Thus, the length of the prism is 14 cm if the volume of the prism is 378 cubic cm and face area is 27 square cm.

Suppose on a certain test, fifty students earn a perfect score and fifty students earn a zero. determine the mean grade and stan
kodGreya [7K]

Answer:

Mean=50.

standard deviation=50.

Step-by-step explanation:

Let the perfect score be 100.

The mean(average) of a data is given by: Mean=\frac{sum of data points}{number of data points}

Here the number of data points are 100. out of which 50 attains a value 100,and 50 attains value 0.

so, sum of data points=50×100+50×0=5000.

Mean=\frac{5000}{100}

Mean=50.

"Now the standard deviation of data points are calculated by firstly subtracting mean from every entry and then square the number and take it as new entry and calculate the mean of the new data entry and lastly taking the square root of this new mean".

Here if 50 is subtracted from each entry the new entry will have 50 entries as '50' and 50 entries as '-50'.

next on squaring we will have all the 100 entries as '2500'.

now the mean of these entries is: \frac{2500\times100}{100}

                                                         =2500

taking it's squareroot we have \sqrt{2500}=50

Hence, standard deviation=50.
